HP Recommended 
good morning
 Being now retired after 42 years at HP (support - last position occupied Support Engineer EMEA Printer Laserjet Pro etc ..), I would like to report a big problem with Firmware 20210202 (available on the HP site).
This installed firmware blocks the WIFI connection regardless of the security protocol (WEP/WAP etc.). issu PFM include in new firmware 20210202
To re-establish a WIFI connection, a firmware downgrade is the only solution:
example: current firmware on the HP site: 20210202 WIFI failure.
               Valid firmware for WIFI connection: lj400mfpM425fw_20140919.rfu
Please escalate this issue to LJ Division for correction.

Best regards
Denis ARGOUD
